DSD

Pressure switch for use with single-line lubrication systems

DSD

DSD sensors are single, mechanical-diaphragm pressure switches. They are used for pressure monitoring and are dependent upon the mechanical design of resulting pressure and preloaded spring force of the pressure spring. Under pressure, a pressure plunger carries the contact washer and moves it to the opposing contact and closes the electrical circuit. If the pressure is reduced by the amount of hysteresis, the switch opens again. On an NC contact, contacts are made in the opposite way. In single-line systems, it can be integrated into metering devices at the end of the lubrication line.
